Long- haul trucking is a likely and obvious place for autonomous vehicles to take hold before they become common as passenger vehicles.

Most exercisers out there are looking to lose some weight and inches off their waist which typically means having to cut down on their food intake. However, there are always hard- gainers out there too – guys who want to put on weight but it doesn't seem to come easy no matter what they try. In many cases, these are guys who work out a lot but simply don’t pack in enough food to gain the weight and build the muscle they’re looking for. If this sounds like you, have a look at the following tips. Go Back To Basics“It’s just simple math,” says Travis Steffen, founder of Workout. BOX. com. There aren’t any crazy strategies necessary for this, and although supplements can help, you might not need them if you eat enough elsewhere. Chances are, you don’t make strict plans to make sure you’re taking in the right number of calories each day, so now you have to always be conscious of it – eat more at meals, schedule snacks throughout the day and focus on foods that have plenty of calories and nutrients, not just one or the other. Foods for Effective Clean- Bulking > > > Keep Everything Consistent. As is the case in most aspects of fitness, consistency is key to bringing about the kind of weight gain you want. To do this in the best way, that means regular exercise with a consistent diet in terms of calories, protein, carbohydrates and fat. ![]() And those are just the basics, since it’s also helpful to be staying hydrated and well rested. The more consistent you are, the more seamless and painless of a process your weight change will be. For example, if you eat chicken breast and two pieces of whole wheat bread with veggies each day and aren't seeing any gains, try adding a bit more chicken and an additional slice of bread. If you're consistent with your intake you'll know exactly when and where to add more food. Foods That Should Be in Every Diet > > > Do What Works for You.

Junk Food: The Best of the Worst > > > PAGE TWO: 3 More Ways to Pack in More Calories > > > . So, even though eating fast food a couple times a day might help you gain the five pounds you want, you probably didn’t envision that weight being all fat. So, like just about any other fitness regimen, there’s a “cheat” day that will come up every once in a while, but just because you’re looking to gain doesn’t mean you can eat whatever at any time you please. Each new week probably won’t bring about too much change in your body, so space out these assessments – you won’t be able to track your gradual weight gain incrementally on a daily basis. Once you get near your weight goal, you can start working out strategies to maintain the weight in the best possible way. Reasons You're Not Building Muscle > > > Go With Dense Foods. Several choices can work, but always look for foods rich in nutrients as well as calories. Klein suggests oatmeal as a good dense carbohydrate, along with brown rice, and rice cakes with peanut butter or almond butter can be high in carbs and protein, while helping you gain weight. Nuts and lean proteins like fish, poultry and eggs are also great for bulking up while staying healthy. ![]() Ways to Gain Muscle > > >.

Yarze, MD, FACP, FACG FASGE., *GI Division, GI Associates of Northern New York, Glens Falls, NY. Purpose: To describe a rare symptomatic complication of peroral colon lavage preparation. Methods: Colonoscopy is now frequently performed as a primary colorectal cancer screening modality. I recently cared for a patient who sustained a rare complication . Upon pre- procedure questioning, the patient mentioned that she had difficulty ingesting the colon lavage preparation, which included magnesium citrate, bisacodyl, and polyethylene glycol solution. Non- bloody vomiting occurred 1. The patient volunteered that the rectal effluent turned from yellow to blackish in color, during the night before which the procedure was performed. She was taking an NSAID intermittently, but this practice was discontinued 5 days prior to presenting for the procedure. There was no recent iron or bismuth ingestion. Physical examination showed slightly pale conjunctivae, but was otherwise unremarkable. We discussed also performing upper GI endoscopy, should it be deemed appropriate upon completing the colonoscopy. The patient was agreeable, and informed consent was obtained for both procedures. The colonoscopy was performed under moderate sedation. The examination was completed to the cecum and the mucosa was coated with melenic residue (which was suctioned and tested overtly positive for blood). The terminal ileal mucosa was similarly coated with black, bloody residue. The colonoscopy was otherwise normal (within the limits of the suboptimal preparation). Given these findings, upper GI endoscopy was then performed. At upper GI endoscopy, a prominent 3 cm nonbleeding Mallory- Weiss tear was found at the EG junction. No endoscopic therapy was deemed necessary, and she was discharged home on a proton- pump inhibitor (4 week course), with instructions to avoid ASA/NSAID use for 4 weeks. A CBC revealed a Hgb of 1. The patient recovered uneventfully. Conclusion: This case highlights a potential, albeit rare complication, which can be seen in association with peroral colon lavage preparation, which was administered prior to screening colonoscopy. Given that screening colonoscopy is now frequently performed, and nausea and vomiting are not a rare occurrence during the preparation, it is possible that such symptomatic events may occur with increasing frequency in the future.

Results: Over the years, I have found many patients who have had cervical esophageal HGM, which endoscopically appeared as 2 . One such case is shown in Figure 1. I have found that in patients with cervical esophageal HGM, the solitary island of gastric tissue is most commonly noted at the 7 to 8 o'clock position (which corresponds to the posterior position).

Markowitz, MD., *GI Division, Gastroenterology Associates of Northern New York, Glens Falls, NY and Department of Radiology, Glens Falls Hospital, Glens Falls, NY. Purpose: To describe an uncommon presentation of hepatic hydrothorax. Methods: A 7. 7 yo male presented with recurrent massive bilateral pleural effusions. Background medical history included systemic hypertension, atrial fibrillation and a remote history of colon carcinoma. He was initially evaluated by my associate 9 months earlier, when abnormal liver biochemical tests were noted. At that time, he had hyperalkalinephosphatasemia (5 ULN). The serum transaminases were . The serum total bilirubin was normal and the albumin was mildly depressed at 3. Full serologic/virologic hepatic investigation was normal aside from the alpha- 1- antitrypsin phenotype revealing MS Pi- type heterozygosity. AMA was specifically negative. An ERCP was performed, which revealed . Liver biopsy revealed . He had no ascites at the time and was to be followed expectantly. He then presented with massive, symptomatic bilateral pleural effusions. He underwent multiple thoracenteses, which showed . Pleuroscopy showed no abnormality, and echocardiography was normal. Consultation was then requested after pleurodesis failed to alleviate the problem. Results: During this evaluation, abdominal CT revealed a . Ultrasound- guided diagnostic paracentesis of a 2 cm RLQ fluid collection confirmed a portal- hypertensive fluid (SAAG = 1. Doppler interrogation of the portal and hepatic venous systems revealed no thrombosis. Radionuclide scanning was performed after 6. Ci of TC9. 9m macroaggregated albumin was injected into the peritoneal cavity (right lower quadrant). This confirmed prompt tracer localization (at 4. Vigorous sodium restriction and combination diuretic therapy were unsuccessful in controlling the pleural fluid accumulation. The patient underwent TIPS placement, which alleviated his bilateral hepatic hydrothoraces. Conclusion: This case highlights an uncommon presentation of hepatic hydrothorax, where pleural fluid accumulation was both bilateral and occurred in the absence of significant ascites. Radionuclide instillation into the peritoneal cavity was employed to facilitate the diagnosis, and TIPS placement successfully alleviated the symptomatic pleural effusions. Top of page. 42. 9 . Yarze, MD, FACP, FACG FASGE., *GI Division, Gastroenterology Associates of Northern New York, Glens Falls, NY. Purpose: To describe the use of . Background history included diverticulosis and she ingested no ASA/NSAID or anticoagulants. Upon presentation, Hb was 1. The patient desired no evaluation, and immediately prior to planned hospital discharge, large volume, bright- red colored, painless hematochezia recurred. On this occasion, she became transiently hypotensive and the Hb fell to 6 g%. A bleeding scan suggested active bleeding from the left colon. EGD was normal. At colonoscopy, pancolonic diverticulosis was noted, but no active bleeding was seen, and ileal intubation was normal. A large adherent clot was seen in the mid- sigmoid. The clot was flushed away and a small- neck diverticulum was noted beneath. A tiny erosion was noted at the neck of the diverticulum, but no visible vessel could be seen. Epinephrine solution was injected at the neck of the diverticulum and the site was marked with ink, as it was thought to be a potential source of bleeding. Bleeding recurred 4. Repeat colonscopy again revealed no active bleeding and no clot was seen in the sigmoid region. A metal clip was placed in the region of the previously placed ink mark, for possible radiologic identification of this area of presumed hemorrhage. Hemodynamically significant bleeding recurred another 3. Results: At angiography, no bleeding site was initially seen on either the SMA or IMA . Hemorrhage was arrested with a third- order . Bleeding has not recurred after a 1. Conclusion: In cases of recurrent, . The former can be used to facilitate identification during repeat endoscopy or surgery, and the latter can be beneficial during angiographic investigation.

All the above interventions were tolerated and diarrhea improved. Six weeks later, she was discharged, having 5 soft, non- bloody bowel actions per day. Twelve weeks after starting adalimumab, prednisone was withdrawn. From the IBD perspective, she remains in clinical remission after 4 months. Conclusion: Transition to adalimumab was successful in achieving and maintaining clinical remission with simultaneous, treatment- refractory Crohn's disease and ITP, with previously demonstrated severe allergy to infliximab. The ITP remained untreatable, and this limited the ability to utilize more traditional medical (6. MP, MTX) and surgical therapies for the underlying IBD. Adalimumab .

By Dietitian, Juliette Kellow BSc RDFollow a diet that’s designed specifically for your blood group and you’ll lose weight, feel healthier and lower your risk of many diseases. At least, that’s what Dr Peter D’Adamo, naturopath and creator of the Blood Type Diet claims in his book Eat Right For Your Blood Type. No wonder then, that it’s been a hit with Hollywood stars like Liz Hurley and Courtney Cox- Arquette, as well as closer- to- home celebrities, like Cheryl Cole, Martine Mc. Cutcheon & Sir Cliff Richard. Cheryl says that it has made such a difference, not so much to her shape, but to how she feels and to her energy levels. Having tried the diet, she now believes that it works, and now watches what she eats, not to stay slim but to feel good. But while Cheryl might be a fan of the Blood Type Diet, most medical and nutrition experts aren’t, and agree that the theory is complete nonsense. So what is the theory? Prepare to be blinded by science! Dr D’Adamo believes our blood group determines how our bodies deal with different nutrients. His theory is based on the idea that each blood group has its own unique antigen marker (a substance that the body recognises as being alien) and this marker reacts badly with certain foods, leading to all sorts of potential health problems. Furthermore, Dr D’Adamo believes that levels of stomach acidity and digestive enzymes are linked with your blood type. Consequently, he says, by following a diet designed specifically for your blood type, your body digests and absorbs food more efficiently, with the result that you lose weight. A list of suggested dog foods for weight loss as prepared by the editors of The Dog Food Advisor. But here’s where the theory becomes even more weird and wonderful. Dr D’Adamo believes that because blood types evolved at different times throughout history, we should eat a diet based on the types of foods our ancestors typically ate at the time when our blood type was first recognised! When did the blood types evolve? Blood Group O was the first blood type to be identified, although how we know this is anyone’s guess – we’re talking about our hunter- gatherer ancestors who were around in 5. B. C! Nevertheless, Dr D’Adamo believes because our type O ancestors survived and thrived on a high- protein, meat- based diet, that’s the type of diet blood group Os should follow in the 2. Next came the emergence of blood type A, sometime around 1. B. C! By this time, our ancestors’ hunter- gathering days were over and instead they started to settle into farming- type communities. The creation of blood type A around this time meant our ancestors did well on a vegetarian- based diet. And again, Dr D’Adamo recommends that blood group A’s should today follow a veggie diet. Blood type B supposedly evolved around 1. The Best Candy for Weight Loss Giving into your sweet tooth could help you lose weight—if you chew, suck, or bite on these lower-calorie candies. A new study reveals the worst foods that make you gain weight and the best foods that help you lose weight. ![]() ![]() B. C thanks to our nomadic ancestors. They left their farms and started wandering the land, constantly moving from place to place. Consequently, Dr D'Adamo's theory goes, blood group B’s today can get away with eating a varied diet that consists of most foods including meat, dairy, grains and vegetables. Finally, came blood type AB, which evolved just 1,0. Dr D'Adamo thinks this blood type helped our ancestors make the transition to modern times. Meaning that people with blood group AB can eat a mixture of the foods suitable for both blood group A and blood group B. That gives me a good idea, but can you be more specific about what you can and can’t eat? Each of the four blood types has a detailed list of foods that should be avoided and those that can be included. Here’s the lowdown. Dr D’Adamo says that our digestive tract retains the memory of ancient times, and so type Os need to eat a typical hunter- gatherer type diet. In other words, type Os should follow a high- protein, low- carb diet with lots of meat and fish but no dairy products, wheat or grains. If that sounds familiar, it’s because it is – the diet recommended for people with blood type O is simply a variation on many of the typical high- protein, low- carb diets that are currently popular, such as the Atkins diet. Foods you can eat freely include meat, fish and olive oil; foods you can eat in moderation include eggs, nuts, seeds, certain vegetables and fruits; and foods to avoid include dairy products, beans, cereals, bread, pasta and rice. To complement your food intake, Dr D’Adamo recommends lots of vigorous aerobic exercise such as aerobics and running – just like our hunter- gatherer ancestors did! ![]() Blood Group AThis is the second most common blood type in the UK. Again according to Dr D'Adamo, digestive system is apparently very good at remembering that our ancestors had settled, farming lifestyles, which included eating lots of grains and vegetables but little meat. Consequently, blood type A’s should follow a vegetarian diet but still avoid dairy products. This means nuts, seeds, beans, cereals, pasta, rice, fruit and veg are all on the . Meanwhile, calming exercises are thought to be best for blood type A’s such as yoga or golf. Blood Group BOnly one person in 1. B – a real shame when you consider this blood group has the least dietary restrictions! TheDietChannel.com provides fast weight loss diet solutions. Use our diet personality quiz to help you in losing weight.As our type B ancestors were able to thrive on all sorts of foods, thanks to all that travelling, very few foods need to be avoided and this is the closest you’ll get to a healthy, balanced diet from Dr D'Adamo. The only foods that need to be avoided are processed foods, although nuts and seeds aren’t recommended and only small amounts of carb- rich foods should be eaten. When it comes to exercise, Dr D’Adamo recommends activities that have mental component, such as hiking, tennis and swimming – clearly our ancestors did a lot of thinking while they were walking! Blood Group ABPeople with this rare blood type should eat a combination of the foods recommended for blood groups A and B. Somewhat confusing when type B allows you to eat most foods, while type A suggests a vegetarian diet! Dr D’Adamo gets around this by suggesting that type ABs follow a veggie diet most of the time with some meat, fish and dairy products occasionally. It’s the same when it comes to exercise too – blood type ABs should combine calming exercises with moderately intense activities. What do the experts say? Medical experts universally agree that the theory is nonsense, and say there is absolutely no link between our blood group and the diet we eat. Consequently you won’t find qualified nutritionists or dietitians recommending this diet. There are also several concerns, namely that the diets recommended for blood groups O and A are considerably limited and cut out major groups of foods. In the long term, this can result in a poor intake of nutrients needed for good health. Cutting out dairy products, for example, will lead to poor intakes of calcium, which can put you at risk of osteoporosis (brittle bone disease), while avoiding meat can result in low intakes of iron, which can lead to anaemia. This is even more worrying in view of the fact that most people in the UK are blood group O or A. But will the diet help me lose weight? Almost certainly, but this is because each of the diets for the four blood types eliminates specific groups of food such as bread and cereals, dairy products or meat and fish. Dr D’Adamo doesn’t give any indication about how much weight you’ll lose, it will depend on how much you restrict your food intake. Are there any pros? Weight-loss goals: Set yourself up for success. Well-planned goals can help you convert your thoughts into action. Here's how to create successful weight-loss goals. When you’re trying to lose weight, sleep may be the last thing on your mind.

Added to this, the blood type diet recommends eating fresh, natural foods and so can help you de- junk your diet by cutting out processed foods, takeaways, booze, chocolate and too many cups of coffee – all of which our ancestors missed out on! And the cons? There are plenty. On a practical level, you may need a blood test to discover your blood group if you don’t already know it – and this will mean a trip to your local health centre! Mealtimes may also be impossible if everyone in the family wants to follow the diet, but has a different blood group! But most importantly, it’s just another cranky way of getting people to cut calories – and the most worrying thing about this is that while you’ll probably lose weight, it could also affect your health in the long term. Nevertheless, if you’re still adamant about giving it a go, it’s best to follow it for just a short time (one week or less) and use it to kick- start a longer- term, healthy, weight- loss plan. Juliette’s verdict. I’m really not a fan of this diet. It’s filled with pseudo- science and has the potential to scare people into avoiding many nutritious foods in an effort to lose weight. It’s also worth bearing in mind that although the diet gives the impression that it’s based on sound scientific research this is, in fact, far from the case. Ultimately, the theory is nonsense. Nevertheless, based on Dr D’Adamo’s theory, I’m looking forward to the evolution of blood type F! People with blood type F will need lots of fast food, takeaways, pizza, sugary snacks, crisps and chocolate to remain in tune with their environment. After all, if the theory is correct, surely that’s what we can expect, based on what many of us now eat in the 2.

The Best Weight Loss Program for 2. Here’s how it works in real life: Our tester was allowed 3. The app helps you keep track, of everything you eat — it’s relatively easy to search by food, restaurant, recipe, or even barcodes scanned off of packaged foods. App users ran into some technical glitches last holiday season, but we experienced no problems. You can find meal suggestions in recipe databases online, in Weight Watchers message boards, through associated books — the list goes on. But our tester’s favorite way to find meal ideas was by scanning the app’s Instagram- like connect feature, where users upload glamor shots of their favorites. You can follow people, browse hashtags, or look for trending topics within. For lunch, our tester could choose between a salad with some tuna fish or an open- faced avocado and balsamic sandwich (both great). Snack fruits like peaches, apples, or pears get you through the long stretches of the day. Dinner consists of a lean protein, a hot vegetable, and a side salad. Eating at chain restaurants is actually easy, because most dishes are already logged into the app. One downside: It’s harder to track your meals at fancy or neighborhood restaurants. You aren’t likely to find in- app points for the locally sourced boar fettuccine, potato- crusted petrale salad, or spicy grilled octopus salad that appeared at our tester’s favorite restaurant. But you can search to see if anyone from the Weight Watchers Community has added a similar meal, or you can estimate how much of each item is in a dish and track it individually, with the option to save the group as a meal for later (3 oz. As a last resort, you can guess and manually enter your meal into the app. Our tester’s grocery cart on a Weight Watchers day included lean meats, vegetables, and packaged Weight Watchers dark chocolate mint ice cream bars. This ability to monitor, measure, and modify with easily understandable points is really what puts the program over the top. Weight Watchers emphasizes that no food is off- limits. But when you see you could spend 3. Chili’s Classic Bacon Burger or have chicken with rice and beans and three beers for the same amount of points, you start to realize the cost certain foods have on your body. A recommended focus on fruits and vegetables (mostly 0 points), lean proteins, and whole grains — which mirrors the advice of our experts — becomes second nature. And, most importantly, our tester didn’t feel too hungry at the end of the day, and learned that small choices throughout the day add up over months of sustained effort. The Weight Watchers app incorporates exercise and its corresponding points. Weight Watchers similarly tracks and incentivizes exercise by assigning users a weekly goal of Fit. Points, which can be synced with tracking devices via the app. Our tester was assigned 2. An hour of low- intensity walking would earn her 7 points, while an hour in a high- intensity spinning class would earn 1. She aced her goals by doing yoga four times a week, and the point tracking kept her motivated to move. Logging food and exercise points might seem annoying: You have to pause your exercise or take time before or after you eat to make sure it gets done. But as business experts often say, what doesn’t get measured doesn’t get managed. You’ll have to measure quite a bit while on Weight Watchers — but the same can be said on any other program where you’re not eating prepackaged food. Speaking of, Weight Watchers has an empire built on prepackaged food — especially in the in- person meetings it offers. The meeting we attended was stocked with water enhancers, snack bars, chips, and food in a pouch for purchase. We tried some and really liked it: The chips with hummus were puffed —a great way to add bulk without calories. And the tikka masala we paired with a cup of rice was shockingly delicious. Plus, we learned something about managing points: After we calculated the points for the rice (6), in retrospect we would’ve eaten just half of a serving size and spent those 3 points elsewhere. That’s a key idea we heard in the Weight Watchers meeting: learning which foods are “worth it” for the points. Weight Watchers’ vegetable tikka masala, one of the standout meals we tasted/tested. At all levels of membership, you weigh yourself once a week to track your progress. Weight Watchers online is $2. You can also shell out $4.

So, there’s a little story behind this one. I spend a lot of time helping beginner and seasoned trainee’s with their questions about health, fitness, and training at the Burn The Fat: Inner Circle fat loss support community. I’ve been a contributor and forum moderator there since 2. I’ve met some pretty cool people. I’ll be honest and up front when I say that one of my personal favorite members is a woman named Jan, who is the ring leader of the Siffer- Ladies! The front elbow plank sans grimacing face. Now, don’t let the cutesy name fool you – these ladies are not your average gym trainee’s. When I picture the Siffer- Ladies showing up at the gym, it’s like an old Western movie where everyone clears out of the bar when the outlaws arrive. The Siffer- Ladies are notorious fitness outlaws! While the so- called “civilized” women are barely breaking a sweat on the Elliptical machine while watching Oprah, the Siffer- Ladies are cranking out endless reps of alligator crawls, ab wheel rollouts, pushups, pullups and partner wheelbarrow walking. They’re hardcore – pure and simple. Some people in their gym even think they’re crazy (I can relate to that!). Jan has been somewhat of a training disciple of mine and she’s built some pretty impressive fitness levels over the years using mostly bodyweight training. You see, Jan is a lifestyle fitness trainee. She’s found something that works for her, and she’s been sticking with it for years. She trains because she loves it. I don’t know what possesses them. Jan contacted me a couple weeks ago asking for advice about getting from 3 minutes to a 5 minute plank. After offering her some suggestions, I’ve been thinking about it ever since. I’ve never had any of my clients do a plank for longer than 3 minutes, and I’ve never done one longer than that either. It’s uncharted territory. So, you know me. The obvious way is to practice more plank exercises like the ones above (and there are many other common variations, too). You can incorporate set/rep schemes throughout your training sessions, or just practice periodically throughout the day (grease the groove technique). You can do pyramid sets, supersets, circuits, or straight sets. The choice is yours, and ultimately your goals will dictate which approach you should take. If you have specific goals, and would like a suggestion, let me know in the comment section below. The plank routine exercises are: front elbow plank (FEP)FEP w/ right arm elevated. FEP w/ left arm elevated. FEP w/ right leg elevated. FEP w/ left leg elevatedright arm and left leg elevatedleft arm and right leg elevatedright side plankleft side plankright side plank with leg upleft side plank with leg uptop of pushup position (TOPP)TOPP w/ right arm up. TOPP w/ left arm up. TOPP w/ right leg up. TOPP w/ left leg up. TOPP w/ right arm and left leg up. TOPP w/ left arm and right leg upright side plank, elbow lockedleft side plank, elbow locked. Here’s a guide for estimating the duration: 3 seconds per exercise = 1 minute total. If you can hold a front elbow plank for at least 3. The fastest way to build up to a 5 minute or longer plank is to work very incrementally on the above exercises – adding only 1 second to each drill at a time, and practicing until it isn’t very difficult (Rating of Perceived Exertion under 6/1. Do keep in mind that you don’t need to follow the above routine verbatim. You can create your circuit any way you like – picking any number of exercises and any duration. You can even add rest times in if you’d like. It’s all dependent on your goals and how much you want to challenge yourself. Important Announcement.

Those isolated from plants and animals were classified as organic. At one time, chemists. The first step in the decline of the vital force theory occurred in 1. Friederich Wohler synthesized urea from inorganic starting materials. Wohler was trying to. NH4. OCN) from silver cyanate (Ag. OCN) and ammonium. ![]() NH4. Cl). What he expected is described by the following equation. Ag. OCN(aq) + NH4. Cl(aq) Ag. Cl(s) + NH4. OCN(aq). The product he isolated from this reaction had none of the properties of cyanate. It was a white, crystalline material that was identical to urea, H2. NCONH2. which could be isolated from urine. Neither Wohler nor his contemporaries claimed that his results disproved the vital. But his results set in motion a series of experiments that led to the. This. inevitably led to the disappearance of . If the difference between organic and inorganic compounds isn't the presence of some. Most compounds extracted from living organisms contain. It is therefore tempting to identify organic chemistry as the chemistry of carbon. Even though organic chemistry focuses on compounds that contain carbon and hydrogen. The special role of carbon in the chemistry of the elements is. The Physical Properties of Carbon Electronic configuration 1s. Electronegativity 2. Covalent radius 0. Carbon has four valence electrons 2s. The. electronegativity of carbon is too small for carbon to gain electrons from most elements. C4- ions, and too large for carbon to lose electrons to form C4+. Carbon therefore forms covalent bonds with a large number of other elements. Because they are relatively small, carbon atoms can come close enough together to form. C=C double bonds or even CC. Carbon also forms strong double and triple bonds to nitrogen and oxygen. It. can even form double bonds to elements such as phosphorus or sulfur that do not form. Several years ago, the unmanned Viking spacecraft carried out experiments designed to. Mars. These experiments were based on the assumption that. Several factors make carbon. No other element can provide the variety of combinations and permutations necessary for. Compounds that contain only carbon and hydrogen are known as hydrocarbons. The simplest alkane is methane: CH4. The Lewis structure of methane can be. Methane is an example of a general rule that carbon is tetravalent; it. To minimize the repulsion. CH. bonds, the geometry around the carbon atom is tetrahedral, as shown in the figure below. The alkane that contains three carbon atoms is known as propane, which has the formula. C3. H8 and the following skeleton structure. The four- carbon alkane is butane, with the formula C4. H1. 0. The names, formulas, and physical properties for a variety of alkanes with the generic. Cn. H2n+2 are given in the table below. The. boiling points of the alkanes gradually increase with the molecular weight of these. At room temperature, the lighter alkanes are gases; the midweight alkanes are. The Saturated Hydrocarbons, or Alkanes Name. Molecular. Formula. Melting. Point (o. C)Boiling. Point (o.

Thus, for every n carbon atoms there must be 2n + 2 hydrogen. Cn. H2n+2. Because two points define a line, the carbon skeleton of the ethane molecule is linear. Because the bond angle in a tetrahedron is 1. The smallest hydrocarbon in which a branch can occur has four carbon atoms. Compounds with the same formula and different structures are known as. Greek isos, . When it was first discovered, the branched isomer with the formula C4. H1. 0. was therefore given the name isobutane. Isobutane. The best way to understand the difference between the structures of butane and. Butane and isobutane are called constitutional isomers because they. One contains two CH3 groups and two CH2. CH3 groups and one CH group. There are three constitutional isomers of pentane, C5. H1. 2. The. first is . A branched isomer is also possible, which was originally named isopentane. When a more. highly branched isomer was discovered, it was named neopentane (the new isomer of. Ball- and- stick models of the three isomers of pentane are shown in the figure below. There are two constitutional isomers with the formula C4. H1. 0. three isomers of C5. H1. 2, and five isomers of C6. H1. 4. There. are over 4 billion isomers for C3. H6. 2, for example. If the carbon chain that forms the backbone of a straight- chain hydrocarbon is long. Cycloalkanes. therefore have two less hydrogen atoms than the parent alkane and a generic formula of Cn. H2n. The angle between adjacent CC bonds is only 6. Cyclopropane is therefore susceptible to chemical reactions that can open up the. Any attempt to force the four carbons that form a cyclobutane ring into a plane of. CC bonds would be 9. One of the four carbon atoms in the cyclobutane ring is therefore displaced from the. The angle between adjacent CC bonds in. Cyclopentane is not a planar molecule, as shown in the figure. By the time we get to the six- membered ring in cyclohexane, a puckered structure can be. One of these carbon atoms is tilted up, out of the. As one looks at the structure of the ethane molecule, it is easy to fall into the trap. Nothing could be further from the. At room temperature, the average velocity of an ethane molecule is about 5. Boeing 7. 47. At the same time, the CH and CC bonds are vibrating. There is another way in which the ethane molecule can move. The CH3 groups. at either end of the molecule can rotate with respect to each around the CC bond. When this happens, the molecule passes. The highest energy conformation corresponds to a structure in which the hydrogen. The lowest energy conformation is a structure in which the hydrogen atoms are. The difference between the eclipsed and staggered conformations of ethane are best. CC bond, as shown in the figure below. The difference between the energies of these conformations is relatively. J/mol. But it is large enough that rotation around the CC bond is not smooth. Although the frequency. The different conformations of a molecule are often described in terms of Newman. These line drawings show the six substituents on the CC bond as if the structure of the molecule was. CC bond in a ball- and- stick model of the. Newman projections for the different staggered conformations of butane are shown. Because of the ease of rotation around CC bonds, there are several conformations of some of the cycloalkanes. Cyclohexane, for example, forms both the. The difference between the energies of the chair conformation, in which the hydrogen. J/mol. As a result, even though the rate at which these two conformations interchange is. Common names such as pentane, isopentane, and neopentane are sufficient to. C5. H1. 2. They. become less useful, however, as the size of the hydrocarbon chain increases. The International Union of Pure and Applied Chemistry (IUPAC) has developed a. Name the. compound as a derivative of the alkane with this number of carbon atoms. The following. compound, for example, is a derivative of pentane because the longest chain contains five. Name the substituents on the chain. Substituents derived from alkanes are named by. This compound contains a methyl (CH3- ). Number the chain starting at the end nearest the first substituent and specify the. Use the lowest possible numbers. This. compound, for example, is 2- methylpentane, not 4- methylpentane. Use the prefixes di- , tri- , and tetra- to describe. Arrange the names of the substituents in alphabetical order. Carbon not only forms the strong CC. C=C double bonds. Compounds that. contain C=C double bonds were once known as olefins (literally, . The simplest alkene has. C2. H4 and the following Lewis structure. The relationship between alkanes and alkenes can be understood by. We start by breaking the bond in an H2. We do the same. thing to one of the bonds between the carbon atoms in an alkene. We then allow the. CH bond. Thus, in theory, we can transform an alkene into the parent alkane by adding an H2. C=C double bond. In practice, this reaction only occurs at high. Because an alkene can be thought of as a derivative of an alkane from which an H2. C=C double bond is Cn. H2n. They were once named by adding the. The IUPAC nomenclature for alkenes names these compounds as derivatives of the parent. The presence of the C=C double bond is indicated by changing the - ane. The location of the C=C double bond in the skeleton structure of the compound is. C=C bond starts. The names of substituents are then added as prefixes to the name of the alkene. Compounds that contain CC triple bonds are called alkynes. These compounds have four. Cn. H2n- 2. The simplest alkyne has the formula C2. H2. and is known by the common name acetylene. The IUPAC nomenclature for alkynes names these compounds as derivatives of the parent. In addition to compounds that contain one double bond (alkenes) or one triple.
